, Referring to the drawing, the numeral 1 is used to designate in general a door mounted 85 within acasement 2 and provided with'the usual latch bolt 3 entering an opening 4 in the adjacent face of the casement to secure the door in closed position. N I

- My invention comprises a plunger shaft 6 slidably and .rotatably mounted within a housing member designated in general by the numeral 7 and mounted within a recess 8 formed inthe'casement. )The shaft is supported at its inner end by a bearing portion 751 9 formed upon the inner end of the housing 7, and the outer end of the shaftis provided with a knob 11 slidably feathered to the shaft 6 and rotatably supported by a face plate 12 threaded or otherwise secured to the outer 8.0,

end of the housing 7 and seated within a recess 13 formed in theouter face of the casement.

The inner; end of the plunger shaft'6 is provided with a latch actuating member 14 rotatably engaging a reduced portion 16 formed'upon said inner end of the shaft, and -l1eld thereon by. a suitable retaining nut 17.

The'member 14 extends laterally into a slot 18 formed in the casement opposite the latch 0.

3 and is provided with a beveled face 19 engaging the beveled end of the latch bolt whereby an axial inward movement of the shaft 6 causes the face 19 to press the latch 3 inwardly to door releasing position, as indicated in dotted lines in Fig. l of the drawing. The member 14 is guided and held against rotation by the slot 18.

A locking member 21 is slidably keyed to the shaft 6 within the housing 7, said member being provided with an annular flange portion 22 seating within a recess 23 formed in an annular locking member 24 slidably and rotatably mounted within the housing. The I member 24 is provided with a pair of apertures 26 preferably arranged upon" opposite sides thereof and slightly offset with respect;

to a diameter passing through the axis of the member 24 and one of said. apertures for a reason, hereinafter more fully explained.

, The member 21' is provided with a pair of notches 27" formed in the periphery of the fiange'portion 22 in-the same relative relation as the apertures 26 and movable to register with said apertures as hereinafter more fully described.

A plate 28 is slidably keyed within the outer end of the housing 7, said plate 28 having a central aperture permitting sliding movement of the shaft 6'therethrough. A pair of pins 29 aresecured upon the plate 28 to extend. inwardly in'parallel relation to the sha'ft6, said pins being arranged in the same relative relation as the apertures 26 and notches 27 whereby said pins may pass through said apertures 26 and notches 27 when in registering relation. The 'inner. ends of the pins 29 extend through apertures 31 formed in a partition 32 mounted within the housing 7 to support and guide the pins in accurately alined positions. Springs 33 are mounted around the pins 29 between the partition 32 and the plate 28 to normally move the plate outwardly against a collar 34 secured upon the shaft 6. The collar 34 abuts against the inner end of a bearing portion '11,'formed upon the knob 11, and a nut 36 threaded onto said portion 11 to retain the knob in operative assembled relation to the face plate 12, thereby limiting the outward movement. of the shaft 6 and plate 28 as actuated by the springs 33.

A collar 37 is mounted upon the locking member .21. The collar 37 is provided with a radially disposed arm 38 arranged to engage a pin 39 extending rearwardly from the inner face of the locking member 24 whereby rotation may be imparted from the collar 37 to the locking member 24. The collar 37 is arranged to be adjustably secured to the locking member 21 'for rotation therewith, preferably by means of a serrated face 41 engaging a correspondingly serrated face of a shoulder 42 carried by the member 21. The collar 37 is normally held in proximate relaand also to change the combination or un-- locking position as indicated by the graduations of the knob 11.

The locking member 21 is provided with an annular flange 44 upon its inner end. A pair of electric contacts 46 are mounted in inwardly extending relation upon the inner end of the housing 7, said contacts extending into slightly spaced relation to the flange 44 when the member 21 is moved with the shaft 6 to its normal outermost position by the springs 33, as shown in Fig. 1 of the drawing. The contacts 46 are insulated from the housing by suitable insulating bushings 47 and conductors 48 and 49 are connected to said-contacts. One of the conductors, as 48,"is.extended directly to an electric bell 51, such as the ordinary door bell, mounted ata point remote from the door. The other conductor is connectedto one side of a source of electrical energy 52, the other side of which is connected to the other terminal of the bell 51 by a conductor 53. t The circuit through the bell is normally broken between the contacts 46, and said circuit is arranged to be closed by moving the flange 44 inwardly to engage the ends of the contactsandthereby bridgethe same to close the circuit. A spring 50 mounted between the member '21 and the inner end of the housing 7'normally moves the member 21 to its extreme forward posi-' tion as defined by stops 55 within the housing. w

' The knob 11 is feathered to the outer end of the shaft 6 in any of a plurality of keyways 54 whereby said knob may be set in any desired angularly adjusted position relative to the shaft. The knob 11 is provided with a dial portion having calibrations 56 marked thereon and readable with respect to a fixed index 57 marked upon the' face plate 12 whereby the knob :11 and shaft 6 may be rotated through desired angles of movement in either direction, the degree of such movement being indicated by the calibrations.

The operating mechanism constructed substantially as illustrated and as above" described is assembled into the housing 7, and the face plate 12 secured thereon. The housing is then inserted into the recess 8 from the front of the casement and secured therein by a plate 58 and securing bolts 59 extending into engagement with the inner end of the hous-- -may be had to the mechanism from inside the door when necessary, but preventing tampering by unauthorized persons from without.-

In operation, the locking members are normally turned with the notches 27 out of registration with the apertures 26, as disclosed in Fig. 4 of the drawing. In this relation, when pressure is applied upon the outwardly extending end of the shaft 6, the shaft is moved inwardly and the inner ends of the pins 29 are moved against the locking members 22 and 24, thereby causing said locking members to be moved inwardly until the flange 44 is moved into contact with the ends of the contacts 46. As the flange 44 bridges the contacts 46, an electric circuit is closed through the bell 51, thereby causing said bell to be operated in the manner and for the purposes of an ordinary door bell. Upon releasing the pressure upon the end of the shaft 6, the springs 33 and 50 return the shaft and the several members connected thereto to normal position.

When it is desired to open the door latch by means of my device, the knob 11 is turned to impart rotation to the shaft 6, thereby causing the arm 38 to swing into engagement with the pin 39 and rotate the locking member 24 to a position with the apertures 26 in axial alinement with the pins 29. This position is indicated by a selected calibration of the dial relative to the index 57. The arm 38 is so disposed relative to the member 21 that when the arm 38 engages the pin 39, the notches 27 will not register with the apertures 26.

When the member 24 has been thus set to proper unlocking position, the dial is turned in the opposite direction, thereby turning the shaft 6 and member 21 in said opposite direction. The member 24 is fitted into the housing 7 sufficiently tight to cause friction to hold the member 24 in adjusted position while the shaft and member 21 are turned in the opposite direction. The shaft and member 21 are turned sufficiently to bring the notches 27 into registering relation with the apertures 26, this position being indicated by another calibration of the dial when moved to register with the index 57. When now pressure is applied upon the outer end of the shaft 6, the shaft is moved inwardly, and the pins 29 are moved to enter and pass through the apertures 26 and notches 27. As the shaft 6 is moved further inwardly, the member 14 is moved to press the latch 3 in wardly to its door releasing position, as indicated in dotted lines in Fig. 1 of the drawing, thereby permitting the door to be opened. As the pins 29 pass through the locking members 21 and 24, said members are not displaced against the pressure of the spring 50, and hence the flange 44 will not be moved to close the circuit through the bell 51. Thus a person possessing the proper combination of numbers to which the knob must be turned, may set the device and open the door without sounding the bell. However,

should a person not in-wpossessionof the proper combination attempt to openthe door in this manner, any inwardmovementof'the shaftfifmade while attempting tomanipulate the dial throughthe proper combinationIwill result in "sounding the bell and advising o'c cupants of. the: apartment that an unauthorized person is attempting to open the door or seeking admission. Inrthis manner, an authorized person may enter without sounding thesbellor disturbing the occupants of the Y apartment, while an unauthorized. person will sound the bell and advise :the occupants of their "presence:-

While'I have illustrated and my invention'j inlo'nly one specific embodiment, the specific details of construction and arrangement are subject to modification in a great variety of ways without departing from the spirit of my invention. I therefore do not wish to be restricted to the specific structure as illustrated and described,'but desire to avail myself of all modifications which may fall within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A door fitting comprising a shaft slidably and rotatably mounted within a door casement; latch actuating means mounted upon the inner end of the shaft; a pair of relatively rotatable locking members rotatably and slidably mounted upon the shaft and having apertures movable to registering .relat-ion when the locking members are in unagainst to close an electric circuit through said contacts.

2. A door fitting comprising a shaft slidably and rotatably mounted within a door casement; latch actuating means mounted upon the inner end of the shaft; a pair of relatively rotatable locking members rotatably and slidably mounted upon the shaft and having apertures movable to registering relation when the locking members are in unlocking relation, one of said members being feathered to the shaft and the other being rotatable relative thereto and frictionally engaged within the easement; means for imparting rotation from the keyed member to the rotatable member; a combination dial feathered upon the outer end of the shaft for turning the shaft and locking members to r unlocking position; pins earned by the shaft and movable axially. therewith to en gage and move the locking members when in locking relation and to pass through the registering apertures without moving the mem-. bers when in unlocking, relation; and a pair of electrical contacts. mounted adjacent the shaft, said contacts being bridged by-one' of said' locking members when .moved axially th'ereagainst byan. inward axial movement ofthe shaft while the locking members are in locking relation. v
